ORRELL ASHTON, 0F SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PA'IERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

PULLINGr-OVER MAOHIN E.

To all whom it may concern:

Be it known that I, ORRELL ASHTON, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Pulling-Over Machines, of which the following description, in connect-ion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to pulling-over machines for shoes and particularly to tip measuring attachments for pulling-over machines of the type shown in United States Letters Patent No. 663,777 granted December 11, 1900 on application of Ronald F. McFeely and similar types in which the top face of the shoe is visible to the operator during the pulling-over operation.

As is well understood, one of the steps in the manufacture of a shoe to be accomplished in the pulling-over operation is the correct positioning of the upper on the last, and particularly on the forepart of the last where the tip seam and the throat or lace opening of the drafted upper require to be located properly in preparation for the detail lasting and fastening of the upper to the sole. With the increasing requirements of the trade for exactness in shoes, hand gages or measuring instruments have been largely employed to supplement the eye of the operator in determining if the tip seam is correctly located longitudinally of the shoe togive the desired length of tip and angularly of the shoe to give the straight position. This latter position is not necessarily at right angles to the median line of the shoe but is usually, in shoes made on crooked lasts, at an oblique angle to the median line and is inclined in one direction on the right shoe and in the opposite direction on a left shoe. Even with the use of hand gages and measures much has been left to the eye of the operator, thus requiring a high degree of skill and judgment on his part while in other respects perfecting of the machine was in progress to reduce the demands upon skill in the operator.

It is the general object of this invention to provide the pulling-over machine with gaging means by which to verify the posi- Specification of Letters Patent.

tion of the tip seam and with relation to which to effect adjustments of the upper to straighten or to obtain correct length of the tip.

An important feature of this invention consists in a gage bar shaped to extend across the forepart of the shoe and mounted on the machine for movement into and out of tip gaging position. Conveniently the gage is mounted to swing toward and from the top face of the shoe and advantageously it is concave to fit over the convex contour of the shoe at the tip seam. This gage is shown as a thin plate having a concave edge and so supported that it has or may have a constant angular relation to the median line of the shoe. This angular relation is important for it is with reference to it that the tip straightening adjustment is made by the usual tip straightening lever and con nections to the side grippers explained in said prior patent. Very crooked lasts 00- cupy different angular positions in the pulling-over machine and provision is made for adjustment of the gage laterally to accommodate such lasts. In this embodiment of the invention the gage is so supported that it will remain by friction or otherwise,.in the operative position to which it is moved and therefore no attention is required from the operator to hold it up while he is making the adjustments of the upper which the gage may show to be necessary.

In accordance with another important feature of this invention a gage, which may or may not have any or all of the characteristics above mentioned is mounted for certain definite adjustments with reference to an end of the shoe to indicate the longitudinal position for the tip on a last of a given size and style for the top length required by the shoe pattern. As shown the gage described mounted upon the heel rest of the pulling-over machine which, as fully de scribed in the British specification covering this improvement on my original pullingover machine, engages the heel end of the shoe during the pulling-over operation. The gage as thus embodied comprises a thin plate the edge of which extends across the forepart of the shoe and which is adjusted with reference to a point of support on the heel engaging rest, to indicate the position Patented June 25, 1912.

lengthwise of the shoe, as well as angularly thereof, for the tip seam of the style of shoe being lasted. The adjustment is provided by making in telescoping sections a rod, one member of which has pivotal connection with the heel rest for movement from an inoperative position and the other member of which supports the gage plate as a transverse arm of the rod. The outer rod member is provided with notches suitably spaced apart for shoe sizes and the inner member has a spring catch to engage in the notches.

A sighting device is movable by the adjustment'over a graduated scale to aid the operator in setting the gage for the size of shoe to be gaged. Reverting to the adjustment of the gage laterally for crooked lasts it may now be explained that this adjustment is preferably made laterally about an axis that is located at the extreme rear end face of the shoe as distinguished from the middle of the forked heel rest or the points at the sides or corners of the heel at which the forked rest engages the shoe. To this end the connect-ion of the gage with the rest in the preferred construction is a sliding one in an are about the end face of the shoe.

' faces of the rest meet the shoe.

The gage is thus arranged to measure from the end face of the heel forwardly along the median line of a crooked last, in any position, to the tip seam and thus to give uniform results both as to length of tips and as to angularity thereof with right and left crooked lasts. The concave face of the gage plate assists the operator in determining the correct lateral adjustment of it for this work. -The gage plate may be made in two lateral parts which are adjustable toward and from each other for narrow and wide lasts so that the gage may always be centered correctly on the last.

Figure lis a side elevation of a portion of a pulling-over machine equipped with this invention and showing the parts more closely associated with the gage; Fig. 2 is a perspective view of the simpler construction of the gage; Figs. 3 and 4 show a further development thereof; Fig. 5 is a plan view of a slightly modified construction.

It may be briefly explained that the machine comprises toe and side grippers 2 and 4 by which the upper is seized and pulled over the last. which is rested against a shoe bottom abutment or sole rest 5 and that a forked heel rest 6 is mounted on a movable carrier by which the rest is yieldingly advanced from a retracted position into engagement with the heel end of the shoe after the grippers have tensioned the upper enough to hold the last firmly against the sole rest. The heel rest can swing laterally to adapt itself automatically to the lateral position, of the shoe heel when the forked The machine further includes a tip straightening hand lever and connections to the side grippers substantially as shown in said prior patent to move one side gripper forwardly and the other backwardly for straightening the tip seam if that seam does not occupy the desired angular relation to the median line of the last. Other adjusting means are also provided for causing the grippers to shift the upper transversely of the last and for drawing the upper forwardly and slacking it backwardly to desired position on the last. The nature and construction of these adjusting mechanisms is not necessary to consider for the purpose of understanding this invention but descriptions thereof will be found in said prior patent mentioned and in the various patents covering improvements upon and developments from the original machine. i

To the heel rest 6, or it might beto the rest carrier 7 by which the heel rest is actuated forwardly I have connected the tip gage. In Fig, 1 this connection is made by a stud 10 screwing into the heel rest frame at the right hand side thereof and furnishing a bearing for a collar 12, Fig. 2, from which extends a tubular rod member 13 which telescopes a rod member 14, the latter being bent laterally at a right angle to present an arm 15 extending transversely across the forepart of the shoe when the gage is in operative position. Upon this bar is secured a thin gage plate 16 the upper edge of which is concave to enable it to fit approximately the contour of the shoe at the tip line. Obviously the arm 15 might be flattened and shaped as described for the plate so that it would fit closely against the shoe and enable the position of the tip seam at all points to be readily compared with it.

The rod member lt has a rearwardly ex tending spring plate 20 attached to it and having a downwardly bent eye portion 22 embracing the tubular member 13 and a finger extension 23. The spring plate 20 is so shaped that it presses firmly against the tubular member at the upper edge of the eye whereby it acts as a pawl and engages notches cut into the top face of member 13 to hold the rod13, lt in lengthwise adjusted position. The finger extension 23 facilitates lifting of the spring plate to disengage it from the notches and permit adjustment. The tubular member 13 is provided on its lower side with a graduated of the supported shoe.

sleeve member 13 could be used alone and the scale omitted if desired as shown in Fig. 4E.

The collar 12 is held from. free rotation on the stud 10 by a spring 25 that clamps it frictionally against a shoulder 26 on the stud. Friction washers 27 may be used if desired. The friction is sutficient to maintain the gage raised against the shoe when it has been lifted to that position by the operator and yet enable it to be easily swung up or down on the stud 10. It will of course be understood that the gage partakes of the automatically effected advancing and retracting movement of the heel rest as well as has the manually effected swinging movement about its stud 10.

In Fig. 3 the stud 101 carrying the collar 121 is connected to the heel rest by a plate 30 that is secured to the upper end of the heel rest fork and furnishes a socket 32 in which the heel rest can turn about an axis that is perpendicular to the plane of the shoe bottom and is in line with the rear end face of the heel of a shoe resting in the heel rest fork. For this purpose the stud 101 has a rearward arm 102 and an upward extension 103'that is clamped frictionally in the socket 32, as by a screw and spring washer, to restrain the gage from free movement about the axis of said socket. The adjust ment provided by the described arrangement allows adjustment of the gage laterally for right and; left crooked lasts. It should be understood that in the pullingover machine it is chiefly the forepart of the shoe that is being operated upon and the forepart is therefore made to occupy a substantially constant position in the machine while the heel part is to be found in different positions according to the shape of the last. The heel rest is made movable laterally to meet this condition and in practice it assumes a shoe resting position at one side of the median line of the machine for a right shoe and at the opposite side for a left shoe and it carries the gage with it. The provision for pivotal movement in the socket 32 permits compensation for these various positions of the heel rest and also permits whatever angular lateral adjustment would otherwise be required or de sired for the gage. The gage plate 16 is herein made adjustable On the lateral arm 15 of the rod ll, as by slots 161 through which screws 162 extend into arm 15.

In Fig. 5 a modified construction is illustrated in which the rod 13, 14 is pivot-ally connected to a stud 105 upon which it is frictionally held and the stud is carried by a bracket 106 that has an are shaped arm 107 that can slide in an arc guideway 108 the center of which is located substantially as the axis of socket 132 in the rear end face A screw 109 holds the parts 107, 108- frictionally. In this figure the arm 151 of rod 13, 14 supports the members 163 of a two part gage plate for adjustment toward and from each other to adapt them for narrow and wide toes. The

adjustment is effected by a right and left threaded bolt 164: having a knurled collar 165 by which to turn it in threaded blocks 166 on plate members 163.

It will be understood that in the contemplated use of the invention the gage will be advanced by the heel rest automatically from its retracted position in time relation with the upper pulling movements of the grippers and that when the machine has come to rest for inspection and adjustment of the upper the operator will position the rest by turning it upwardly about the stud 10 and swinging it laterally as may be suitable for the particular right or left shoe if the construction shown in Figs. 3 and 5 is used. The adjustment of rod members 13,

'14 having been made for the length of the shoe, or more correctly speaking, for the length of the tip required for the style and size of the shoe the operator compares the lengthwise'and angular position of the tip seam with that indicated for it by the gage plate 16, or 163, and then makes by the tip straightening lever 292 or otherwise the cor rections required to locate the tip seam where it should be. Before restarting the machine the gage is turned down again to a position where it will be out of the way of the other parts of the machine and where it will not interfere with the insertion and removal of shoes.
